TOOL-HANDLE.

SPECIFICATION forming; part of Letters Patent No. 286,124, dated October2, 1883.

Application filed April 27, 188$.(No model.)

To all whom it may concern:

Be it known that I, ERAWFORD M. FAIR- BANKS, of Pawtucket, in the State of Rhode Island, have made certain new and useful In1- provements in Tool-Handles; and I do hereby declare that the following specification, taken in connection with the drawings making a part of the same, is a full, clear, and exact description thereof.

I Figure 1 is a section of, the handle, showing device for and manner of attaching the tool. Fig. 2 is an edge or side view of the tool and holder. Fig. 3 is an edge view of a portion of a tool with the tang thereof having a modified form of end for engagement in the toolholder.

The object of my invention is to produce a tool-handle which may beused upon a variety of tools having similarly-formal tangs, and which is capable of being attached and detached at pleasure; and it consists in the de vices for holding and securing the tool, hereinalter described.

In the drawings, A is a llle, having a tang, B.

(l is the handle, which. is usually made of wood, although other materials may be used, if desired, which is bored out a suitable distance, as shown, and provided with a ferrule, Il at its smaller end, which may extend slight ly beyond the wood. .lhrough the handle is a hole or opening, 10, into which a nut, F, is introduced and forced inward until the hole in the nut isbrought into line with the lengthwise hole in the handle. The tool at the butt end has shoulders G G upon either side of the tang, the latter terminating in a ball or rim ol'increased diameter, or in a corrugation for the same purpose, as shown in Fig. 3.

H the tool-holder, having upon its tailpiece I a screw-thread, and having its head J slotted or divided into two prongs, the bottom of such slot being enlarged to receive the enlarged end of the tang when slipped in horizontall y.

Taking the parts substantially as described, the operation of my invention is as follows:

The end of the tang B is inserted in the head of the holder H, as shown in .Fig. 2. This being done, the tang and holder are inserted in the handle 0 and the tail of the latter caused to engage the nut F. As the tool isrotated it is drawn down into the handle by the nut F until the shoulders G G- come in contact with the ferrule, when a slight further rotation will put a strainupon the tang, will be readily k seen, which will rigidly hold the tool in position. W'hen it is desired to remove the tool, it is simply turned in the opposite direction until the tail of the holder II is released from the nut F, when the whole can be removed and the tool detached from the holder; or the hole in the handle maybe made suiiiciently large to permit the removal of the tang from the holder after a low turns to release the tension. I

The manner of holding theiool through the resistance of the shoulders (i (i against the .pull exerted upon the end of the tang B, as

to secure by Letters Patent, is

The combination of the tool .A, having a tang terminating in a ball, corrugation, or enlarged .rim, with a holder, H, slotted or, divided into two prongs, having an enlarged cavity at the base of the opening or slot be tween the prongs for the reception of the end of the tang, the nut F, inserted in an opening in the handle, and with the said handle, all substantial] as and for the purposeherein set forth.
